Which function is specifically used to count non-empty cells?

The function that is specifically used to count non-empty cells is CountA. This function is designed to tally all cells within a specified range that contain any type of data, including text, numbers, logical values, errors, and even formula results that yield non-empty responses.

CountA is useful in various scenarios, such as when you need to determine how many entries have been made in a survey or how many products are listed in a catalog, irrespective of the type of data contained within those cells. This comprehensive counting of non-empty cells allows for a wide view of data presence in a spreadsheet situation.

In contrast, the other functions have different specific uses: Count is mostly used to count only cells with numeric values, CountBlank counts only the empty cells, while Sum calculates the total of numeric values in the specified range. Each of these has its own distinct application that does not include counting non-empty cells, which solidifies CountA's position as the suitable choice here.
